Chicago wheat prices increased on Monday due to bargain buying after a sharp decline on Friday, which was influenced by improved weather in major growing regions like Russia and the U.S. Soybeans and corn also experienced price rebounds, partially recovering from Friday's losses. The market faces pressure from expectations of a large Australian crop despite some weather damage and weak demand. Uncertainty arises from Russian export restrictions, as Russian grain exporters plan to sell directly to sovereign buyers, complicating foreign trading subsidiaries' roles. This could benefit other wheat origins if Russia loses sales in tenders due to its minimum export price policy.
